Actor Kelsey Grammer’s ex-wife says she became embroiled in a heated argument with Dimitri Charalambopoulos after he received an early-morning text and a phone call from a screaming woman.

The dispute, which allegedly happened as Grammer was recovering from cancer treatment in Houston, reportedly turned violent. (Grammer was diagnosed with endometrial cancer and underwent a hysterectomy, US magazine reports.)

Grammer states she was left pleading for mercy after Charalambopoulos allegedly pulled her hair and pushed her head against the bed.

She submitted photos of bruising to her arms and face to Houston police as they investigated the assault claim, and on Friday, prosecutors at the Harris County District Attorney’s Office filed a felony charge of assault of a family member and impeding breath against him.

Charalambopoulos, a former attorney-turned-fitness trainer, was not arrested, but appeared in court on Monday, when he posted bond of $5,000.

He has denied the charge and a statement from his lawyer Kirk Lechtenberger, released to AccessHollywood.com, reads: “Unfortunately, the Houston Police Department filed a case against Mr. Dimitri Charalambopoulos notwithstanding the fact that no offense ever happened. This action is not unexpected considering that, in this day and age, anyone can make up anything and get a charge filed. We look forward to going to trial as soon as possible and clearing this innocent man of this false allegation.”

Camille Grammer obtained a temporary restraining order against Charalambopoulos in a California court days after the alleged incident, but a hearing regarding the protective ban has been postponed until Dec. 10.
